2 Stroke Engines

With nearly 30 years 2 cycle engine experience, at Buller Built we know what is required to build winning engines. Look inside one of our motors and you will clearly see the quality of workmanship and detail that goes into building an Open or Blueprinting a stock engine. Extensive dyno, flow bench and track testing has been done by Buller Built when developing our engine packages.

Included with each motor is complete break-in instructions, a detailed set up sheet dealing with pipe, air density, clutch, fuel, temp, oil, RPM and maintenance recommendations.

For we will break in your motor on our computerized dyno/ accelermeter and supply you with a print out.

Listed below are our most popular engine packages. We have experience with nearly every 2 Stroke engine made. If you have a question about your particular engine please give us a call.

The 125cc Parilla Sudam engine is an amazing engine package. This engine built as an open with dual carbs and stroked crank is capable of a reliable 55+ horsepower.

We offer the Sudam at various levels of horsepower depending on your class structure. The base package at approximately 38 horse is the stock Sudam as it comes from IAME and is less a carb.

The next level would be the Blueprinted Sudam which is approximately 41 to 44 horsepower with a single blueprinted carb, depending on fuel.

We then offer the engine as an Open with single or dual carb setup which is approximately 44 to 48 horsepower, again depending on the carb/fuel combination.

Then the ultimate, built as an open with a stroked crank and dual Tillotson carb assembly at 55+ horsepower.

With each modified engine package the cases are cut and contoured to maximize air flow to the cylinder. The cylinder has the port timings, sizes, angles and volumes precisely adjusted to combinations that we have found to work best in conjunction with each other. The reed cage is modified for increased flow. Each engine is dynoed (except stock engine less carb) and includes a dyno print out.
